What if I'm on an older version of Firefox?

Firefox joins other modern browsers like Google Chrome and Microsoft Edge by removing support for these NPAPI plugins. Now, many sites have adopted Web APIs, and almost all your favorite pages can be enjoyed without using old and insecure plugins. Web APIs are designed to replace the function of the NPAPI plugins without undermining your internet security, stability and performance.īefore, while these Web APIs weren’t quite ready, Firefox started to transition by making plugins load manually ( click to activate).

Over the past few years, Firefox has worked hard to build replacements for these plugins, these replacements are called Web APIs. While NPAPI plugins, especially Flash, have helped enable these interactive pages, they also make your browsing slower, less secure and more likely to crash. The internet is full of websites that go beyond static pages, such as video, sound and games. Over the past few years, Firefox has implemented various Web APIs so that websites can do the same things they’ve always done without plugins, so you will most likely not notice any change to your browsing experience.

T o try using an older browser version, you can refer to the instructions available at the following link: If you are able to utilize an older browser version that still supports Adobe Flash, then you may still be able to utilize the MarkView Viewer on versions <= 9.x.
